A Good Snackby David Florea

On Saturday morning, Bob wanted to play video games, but also wanted a snack to eat along with it. So he drove to Target and got a bag of chips. Then he started to play video games. There were 40 chips in the bag, and he ate 15 chips in 8 minutes, faster and faster. Then, after 8 minutes he stopped because he was full, and did not eat any chips for 4 minutes. 12 minutes after he started, he continued eating the remaining 25 chips. He did it in 4.5 minutes by eating the last chips at a constant rate. It took him 16.5 minutes to eat all 40 chips.
